We know there are many speech therapists that use the PowerLung in their practice but we are not aware of the conditions for which they use the PowerLung.

For their purposes, they typically use the PowerLung Performer Series models. The most commonly used are P617B or M422T. If you are not active in exercise or sports training the M422T may work best for you.
